Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola

Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola was established on 20th October, 1969 with its head-quarter at Akola. This Agricultural University was named after the illustrious son of Vidarbha Dr. Panjabrao (alias Bhausaheb) Deshmukh, who was the Minister for Agriculture,Govt. of India. The jurisdiction of this university is spread over the eleven districts of Vidarbha. According to the University Act 1983 (of the Government of Maharashtra), the University is entrusted with the responsibility of agricultural education, research and extension education alongwith breeder and foundation seed programme. The University has its main campus at Akola. The instructional programmes at main campus are spread over in 5 Colleges namely, College of Agriculture, College of Agricultural Engineering & Technology, College of Forestry, College of Horticulture and Post Graduate Institute. At this campus 4 degree programmes namely B.Sc.(Agri.) B.Sc. (Hort.), B.Sc. (Forestry) and B.Tech. (Ag. Engg.) , two Master’s Degree Programmes viz. M.Sc.(Agri.) and M.Tech. (Agri.Engg.) and Doctoral Degree Programmes in the faculties of Agriculture and Agril. Engineering are offered. The University has its sub-campus at Nagpur with constituent College, College of Agriculture which offers B.Sc.(Agri.) and M.Sc.(Agri.) degree programmes. The Nagpur Campus is accomplished with a garden, surrounded by its natural beauty and a well established Zoo which attract the general public and visitors to the city. A separate botanic Garden is being maintained on 22 hectares with a green house for the benefit of research workers. In addition there are 2 affiliated grant-in-aid colleges and 14 private non-grant-in-aid colleges under the umbrella of this University A Central Research Station is situated at the main Campus which caters to the need of research projects undertaken by Crop Scientists of the principle crops of the region are Cotton, Sorghum, Oilseeds and Pulses.

    EFFECT OF TILLAGE AND IPNS ON SOIL PROPERTIES, UPTAKE OF NUTRIENTS AND PRODUCTIVITY OF SOYBEN – COTTON ROTATION IN VERTISOL.
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-09-23) AGE, ASHOK BHAGWAN.; Kadu, Dr. P. R.
    The present investigation was conducted during kharif 2016-17 and 2017-18 with a view to study the “ Effect of tillage and IPNS on soil properties, uptake of nutrients and productivity of soybean-cotton rotation in Vertisol” executed at Research Farm, Department of Soil Science and Agricultural Chemistry, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola with an objectives to study the effect of tillage and IPNS on physical, chemical and biological properties of soil, to assess the effect of tillage and IPNS on yield and nutrient uptake by soybean. To find out the effect of tillage and IPNS on yield and nutrient uptake by cotton. The experiment was carried out with main plot comprises two treatments i.e. conservation tillage (one harrowing and two weeding) and conventional tillage (one ploughing , one harrowing, two hoeing and two hand weeding) and eight sub plot treatments of integrated plant nutrient system consisting of control, 100 per cent RDF and use of chemical fertilizer along with organic source of nutrient in which 50 per cent N applied through organic sources (FYM, wheat straw, glyricidia leaf manuring (GLM), composted cotton straw, vermicompost and phosphocompost) and remaining N was applied through chemical fertilizers. The experiment was framed in randomised block design with three replications. The soil and plant samples were analysed after each crop during 2016-17 and 2017-18. Similarly the apparent nutrient balance, soil quality index and cost economics were also computed. The use of organics viz. FYM, GLM, phosphocompost and vermicompost in conjunction with chemical fertilizers registered improvement in physical properties viz. bulk density, HC, MWD, and soil moisture content after harvest of both crop under conservation tillage. Significantly higher soil organic carbon, available N, P, K, S and micronutrients were recorded with the conjunctive use of organics viz. FYM, GLM, phosphocompost and vermicompost along with chemical fertilizers under conservation tillage during both the year. The biological properties viz. SMBC, SMBN, CO2 evolution and DHA were improved significantly under various IPNS treatments comprising use of FYM, phoshpocompost, GLM, and vermicompost amalgamated with chemical fertilizers under conservation tillage. The significantly highest soybean seed yield and seed cotton yield as well as highest uptake of nutrients were recorded with the application of phosphocompost in conjunction with chemical fertilizers followed by FYM, GLM and vermicompost under conservation tillage. Among the tillage practices, the conservation tillage was found beneficial in improving physical, chemical and biological properties of soil. Similarly, significantly higher soybean and cotton yield and uptake of nutrients were recorded in conservation tillage as compared to conventional tillage under soybean-cotton rotation. The apparent nutrient balances of major nutrients were assessed. The lowest negative balance of N and K was observed with application of composted cotton stalk. While the highest P balance was noted with the application of wheat straw. The soil quality index was assessed based on 24 soil parameters. Principal component analysis (PCA) was run to arrived at component values. The significantly highest SQI was observed with FYM followed by GLM and phosphocompost. However, among the tillage practices, conservation tillage was recorded higher soil quality index as compared to conventional tillage. The B:C ratio was noted highest in conservation tillage as compared to conventional tillage. Among the various IPNS treatments the use of FYM and Phosphocompost was found equally beneficial for achieving higher B:C ratio. The results obtained will serve as a benchmark database for further monitoring of soil quality and sustainability of crop production under soybean-cotton rotation in Vertisols.
